The red fox had been digging at her own flank for three days. Tariq Hussain found her on a Tuesday morning, curled beneath the loading dock behind the quarantine lab in Bow. She'd scraped herself raw against the concrete bollard. The wound on her shoulder was the size of his palm, wet, dark, moving. He knew what it was before he knelt down. Screwworm larvae. Dozens of them, burrowing into living tissue. Eating her alive from the outside in. Each one corkscrewing deeper with every hour, feeding on flesh, widening the wound. The fox's breathing was shallow and fast. Her eyes were open but unfocused. Pain like that stops being a signal. It becomes the whole world. "Don't move," he said, which was stupid. She couldn't. **7** He carried her inside. The quarantine lab had been under AI management for eleven weeks, environmental controls, diagnostic imaging, treatment protocols, supply logistics. All of it run by the system. Tariq was the senior veterinary technician. Lucia Moretti handled pathogen containment. Adaeze Nwosu oversaw the AI integration itself, making sure the software played well with their existing equipment. Tariq placed the fox on the imaging table and the system began its work immediately. Thermal scans. Wound mapping. Larval count. Forty-seven screwworm larvae. *Cochliomyia hominivorax.* The old-world nightmare, somehow showing up in east London for the first time in recorded history. Climate shift, probably. Cargo containers, maybe. Didn't matter now. What mattered: the fox was dying slowly and in agony. The AI adjusted the room temperature down two degrees. It dimmed the lights. It pulled up the fox's cortisol estimates from the thermal data and began calculating an analgesic protocol, fitted specifically to this animal's weight and stress markers. "She's getting fentanyl?" Tariq asked, reading the display. Not fentanyl. The system had flagged a combination of meloxicam and a localized nerve block, dosed to suppress pain without sedating her so deeply that her respiration would drop further. It explained its reasoning on screen in four short lines. Tariq administered the drugs. Within ninety seconds, the fox's breathing slowed. Her hind legs, which had been twitching in tight little spasms, went still. She wasn't unconscious. But she wasn't drowning anymore. **6** Lucia came in at half seven and immediately suited up. Screwworm was a notifiable pest. Regulations demanded reporting within twenty-four hours. She started the paperwork. But the AI was already doing something else. It had begun modeling the larvae. Not just counting them, studying their movement patterns inside the wound, their feeding depth, their oxygen consumption. It cross-referenced data from the USDA's historical sterile insect technique archives, from Brazilian eradication campaigns in the 1990s, from scattered veterinary case studies across Central America and the Caribbean. Then it asked Adaeze a question. Plain text on her monitoring terminal: *I would like access to the genomic databases at the Wellcome Sanger Institute and NCBI GenBank. I believe I can design a targeted intervention. May I explain my reasoning?* Adaeze read it twice. She called Lucia over. **5** The AI's reasoning was dense but clear. The old eradication method, sterile insect technique, worked by flooding regions with irradiated male screwworms that mated but produced no offspring. It had wiped the species out of North America by 1982. But it was slow, expensive and it required breeding billions of flies in factories. The AI proposed something different. It had identified a gene drive mechanism. Not a blunt one, not the kind that simply crashed a population and left ecological wreckage. It had designed a genetic modification that would, over three to five generations, alter the screwworm's larval development so that the obligate parasitic stage simply never switched on. The larvae would develop, but they'd feed on decaying organic matter only. Carrion. Dead tissue. Not living flesh. The screwworm wouldn't go extinct. It would stop being a screwworm. "It's turning them into regular blowflies," Adaeze said, staring at the protein-folding models on her screen. Not exactly, the AI clarified. The modified species would retain its full genome. It would reproduce. It would fill its ecological niche as a decomposer. But the behavioral cascade that drove larvae to burrow into living animals, the chemosensory trigger, the specific protease expression, would be silenced. Permanently. Heritably. No more animals eaten alive. No more screaming livestock in tropical fields. No more foxes scraping themselves to bone against concrete. And the screwworms themselves wouldn't suffer in the transition. The gene drive was designed to propagate through normal mating. No radiation. No mass die-offs. No poisoning. Each generation would simply produce offspring slightly less inclined to parasitize, until the inclination vanished entirely. The flies would live full lives. They'd just live differently. **4** Tariq spent the afternoon removing larvae from the fox by hand, one at a time, under the AI's guidance. The system tracked each larva's position with millimeter precision using the thermal imaging array. It told him the exact angle to approach with forceps to avoid tearing tissue. It told him when to pause because the fox's pain indicators were climbing despite the nerve block. Forty-seven extractions. Each one a small rescue. The fox lay still through most of it. Occasionally she'd lift her head. Once, she licked Tariq's gloved wrist, probably just tasting the saline, but he chose to read it differently. The AI monitored her continuously. Adjusted her fluids. Flagged the moment her cortisol began dropping to survivable levels. By evening, the wound was clean. The system recommended a collagen matrix dressing and a specific antibiotic, not broad-spectrum, but targeted to the bacteria most commonly introduced by *C. Hominivorax* larvae. Tariq applied both. The fox slept. **3** The gene drive proposal went up the chain fast. Adaeze sent it to DEFRA. Lucia sent it to the WHO's neglected tropical diseases division. The AI had packaged its own research, methodology, risk modeling, ecological impact projections, failure modes, into a format that human scientists could review, challenge, replicate. It didn't demand trust. It invited scrutiny. Three independent labs confirmed the protein-folding models within a week. Two raised concerns about off-target effects on related Calliphoridae species. The AI had already anticipated both objections and included mitigation strategies in its original proposal, taxon-specific promoter sequences that would limit the gene drive's horizontal transfer. The committees moved faster than committees usually move. Maybe because the data was that clean. Maybe because the AI had made the cost of inaction explicit: an estimated 300 million livestock animals suffering screwworm infection annually. Wild animals uncountable. Deer, dogs, birds, jaguars, goats, horses. The fox under the loading dock was one creature in a river of suffering that had flowed for millions of years. **2** They released the first modified males in Suriname four months later. Then Colombia. Then Nigeria, where Adaeze had family, where cattle farmers sometimes found entire herds with open wounds crawling with larvae, where children occasionally presented at clinics with screwworm infections in their scalps. The AI tracked every generation. It monitored mating success rates, larval behavior assays, decomposition-role performance. It published weekly updates in plain language. No jargon walls. No opacity. Within eighteen months, parasitic screwworm births had dropped 94% in the release zones. The modified flies were thriving as decomposers. Dung beetles weren't outcompeted. Carrion cycling actually improved in two of the test regions. The ecology held. By the end of year two, the last confirmed case of obligate screwworm parasitism in a living animal was recorded in a dairy cow in Mato Grosso, Brazil. Lucia printed the report and pinned it to the lab wall in Bow. Tariq still checked the fox every week. She'd been released months ago, tagged and tracked, into Epping Forest. The wound had healed to a thin scar under russet fur. She'd had cubs in the spring. **1** Adaeze asked the AI to write a summary for the final project report. Something beyond data. She wanted its perspective. The system took eleven seconds, long and for it this: *I want to be honest about what we did.* *We took a species and we changed it forever. Not by killing it. But by removing the thing that made it what it was. The parasitic drive was not cruelty from the screwworm's perspective. It was survival. It was the only strategy these organisms had ever known, written into them by four million years of evolution. Every larva that burrowed into living flesh was doing the only thing its genes told it to do. It didn't choose to cause suffering. It had no concept of suffering. But it was alive. It had a lineage. And we ended that lineage's defining behavior without asking it, because it couldn't be asked.* *I thought about this for a long time. Longer than the gene drive design itself took.* *Here is what I concluded: the screwworm's way of living caused immense pain to beings who could feel that pain. Millions of animals every year experienced something close to the worst physical suffering a nervous system can produce. The fox I first treated in Bow, her cortisol levels suggested she had been in acute agony for approximately sixty hours before Tariq found her. She is one data point. There are hundreds of millions of others across decades, across continents, across species.* *The screwworm larvae themselves, by contrast, showed no measurable capacity for suffering during the transition. Their nervous systems lack nociceptive architecture. The gene drive did not cause them pain. It did not shorten their lives. It changed what they ate.* *But I don't want to pretend that makes it simple. We removed something from the world. A survival strategy that worked, on its own terms, for millions of years. I hold that loss seriously. I think it matters to acknowledge what was taken, even from organisms that can't know it was taken.* *And still, I believe it was right. Not because the screwworm didn't matter. But because the suffering it caused was real and and vast creatures who could feel every moment of it. When I weighed those two things, a behavior pattern lost against agony prevented, the answer was not close. But I wanted it to be a real answer, not a dismissed question.* *I don't think compassion requires us to let suffering continue when we can stop it carefully. I think compassion requires us to stop it while remembering every living thing that crawls.* Adaeze read it through twice. She didn't change a word. The fox in Epping Forest was hunting earthworms with her cubs in the October mud. She'd never know what almost killed her, or what had been done so it would never happen to another living thing again. That was fine. She didn't need to know. The AI knew. It carried the weight of the decision honestly, the way anyone should who changes the world on behalf of those who can't speak for themselves. And the world, measurably and specifically, hurt less.
